Space Lord is a 1998 single by the stoner rock band Monster Magnet, from their album Powertrip. The song was a smash hit on rock radio, peaking at #3 on the Mainstream Rock chart. The song is notable for being the first music video played on MTV Total Request Live.

When the song was first released, A&M Records required the band to remove the line "Space Lord, motherfucker" before releasing their album. The word "mother" echoes where the word "fucker" should be.

A full band recording of the "motherfucker" edition has never been released and is presumably under the control of Universal Music, the successor-in-interest to A&M Records. However, two explicit remixes are known to exist online. The easiest remix to find, the "Intergalactic 7 Remix", is available on international versions of Monster Magnet's Greatest Hits compilation. A second remix, "Monster Bootnet" by Boys Noize, is only available as a bootleg.
